He's got plenty of speed early (and late) Kevin. There's only one scenario I'm worried about regarding the bet and that's 4 pegs. If he's 3 pegs I'm confident the 2 in front (which would likely be the 1 & 2) will take him far enough into the straight for him to show his speed.....if DeFilippi snags back at the start I'm sure he's classy & versatile enough to then figure in the finish and the other scenario is the one u mentioned.....an early speed burn where he pops off into the running line.
I usually don't bet each way but the B365 win price of $8 seems real good value for a bloke whose won gold or silver in 27 of 38 starts. May have to include a small win wager.
Final note: Stents kiwi form is 10-12 lengths superior to that of Flying Isa. It's just a question of how far has Luke improved him?
